TH8065
Voltage Regulator with LIN Transceiver and Watchdog
5.9 Undervoltage VSUP
The combination of dynamic power on reset and low voltage reset guarantees a defined start up behaviour.
If the supply voltage VSUP drops below 3V the low voltage detection becomes active. If the VSUP voltage
rises again above 3.5V the low voltage reset will be terminated and the 5V voltage regulator will be started.
5.10 Short circuit RxD, RESET against GND or VCC
Both outputs are short circuit proof to VCC and ground.
5.11 Short circuit CWD against GND or VCC
The watchdog is deactivated if CWD is short circuit against GND. The reset signal is in this case only
determined by the thresholds.
If WDI is short circuit against VCC the reset pin outputs a permanent low level.
